virtual void | Initialize (Assignment *const assignment)=0 |
This method is called to initialize the solution pool with the assignment from the local search. More... | |
virtual void | RegisterNewSolution (Assignment *const assignment)=0 |
This method is called when a new solution has been accepted by the local search. More... | |
virtual void | GetNextSolution (Assignment *const assignment)=0 |
This method is called when the local search starts a new neighborhood to initialize the default assignment. More... | |
